I have Athom mini relays with my physical switches. They work independent of Home Assistant, and leave the physical light switch in place.
It's on my bucket list to try and find a way to cram a full shim of an Australian Clipsal style light switch with a no neutral wifi and relay module so you can do this by just replacing the switch plates (as it is it's my way or going with capacitive touch).
